I know the IMDT (Institute of Modern Dog Trainers) are starting online courses and Fenzi Dog Academy courses are online. They may be worth looking at. I'm not sure if they do behavioural stuff or just training though.

I've looked at the Sarah Whitehead Think Dog courses. Like you, something for the future but not sure what's good or not.
As H has developed fears I'd like to understand more, in general as well as his fears.

Courses through the IMDT and APDT, which links to Sarah Whitehead's website, would be my recommended route and their courses are all accredited by the Open College Network, so standards for the courses and the marking are maintained and monitored. I'm currently studying the Think Dog! Certificate and really enjoying it.

I've been keeping a training log of my experience of the course which may give you a little more insight on what to expect. Happy to answer and questions, if I can

I'm currently reading around dog aggression for my next assignment, so watching quite a lot of videos as well to help identify 'aggression' . I've even signed up for a practical 2 day course which gives hands on experience of working with dogs in a rescue centre, under the guidance of course tutors
